GENERAL FEATURES
SINCRO RD1 is a digital voltage regulator designed for 50/60 Hz brushes generators.
It regulates the output voltage of a generator by controlling the field current.
It has single and three phase sensing.
RD1 is powered by an auxiliary circuit on the main stator.
The RD1 controls and keeps constant the average value of the 3RMS phase voltages.
A frequency measuring circuit continually monitors the alternator output and provides output under-
speed protection of the excitation system, by reducing the output voltage proportionally with speed
below a pre-settable threshold. A manual adjustment is provided for factory setting of the under
frequency roll off point, (UF). This can easily be changed to 50 or 60 Hz with two dip switches.
